<br />page-6 <br />swallows were observed only flying over reclaimed and mountain <br />shrub habitats. <br />Cavity Nesters - Pickers and Gleaners: <br />1985 <br />This guild includes birds that nest in cavities and glean <br />food from branches and leaves. They were most numerous on the <br />aspen habitats (P=0.01). House wrens were the most numerous <br />birds on the aspen sites where extremely high densities were <br />present. The highest density occurred on aspen-edge sites which <br />was higher (P=0.02) than on reclaimed sites. House wren density <br />on the aspen sites was much higher than on the reclaimed sites <br />but was not significantly different. One house wren nest was <br />found in a small dead aspen in a tree pad in one of the reclaimed <br />sites, but most of those observed on reclaimed-edge sites were <br />near the aspen trees. Red-breasted and white-breasted nuthatches <br />were uncommon and counted only on one of the aspen sites. Most of <br />the black-capped chickadees were counted on aspen sites but the <br />density of these birds were not different (P=0.53) among <br />habitats. <br />1986 <br />House wrens were again the most numerous member of the guild, <br />and the highest density occurred on the aspen habitats. None <br />were observed on the reclaimed habitats, but the density was not <br />different from mountain shrub. Few blackpped ~~chickad~~ss... were <br />observed on mountain shrub and none on the reclaim habitats, <br />but the density was not different (P=0.44). Few red- and <br />white-breasted nut h` at_hes were observed on the aspen habitats. <br />Cavity Nesters - Ground feeders: <br />1985 <br />Most birds in this guild were observed in aspen-edge habitat, <br />although the density was different (P=0.03) only from the <br />reclaimed sites. Mountain bluebird was the only bird within the <br />guild with significant differences (P=0.03). Several mountain <br />bluebirds were observed on the reclaimed-edge habitat as they fed <br />on the ground or perched on dead forbs, but nesting probably <br />occurred in the adjacent aspen. Densities of American kestrels <br />(P=0.69), northern flickers (P=0.08), and European starlings <br />(P=0.64) were not different among habitats. <br />1986 <br />The density of these birds was not different among habitats <br />(P=0.08) although northern flickers (P=0.04) were more numerous <br />on the aspen than on the reclaimed habitats. Mountain bluebird, <br />American robin, and European starling densities were not <br />different among habitats. <br />
